They developed a number of adaptations -- from those crushing claws that snagged the hapless Lechriapsis, to flattened tails for swimming, as well as primitive lungs and strange, filter-feeding appendages.

他们进化出了许多适应性——从那些抓住倒霉的 Lechriapsis 的压碎的爪子，到适合游泳的扁平尾巴，以及原始的肺和奇怪的滤食性附肢。

But having a larger passageway that sits closer to where the lungs are in today's lunged fish is a good sign that both Tiktaalik and Ichthyostega had some sort of primitive lungs.

但是，在今天的带肺鱼类中，有一条更大的通道更靠近肺部，这是一个很好的迹象，表明提塔利克鱼和鱼石藻都有某种原始的肺部。
